7776-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7776-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7776-66:
(6*7)+(5*7)+(4*7)+(3*6)+(2*6)+(1*6)=141
141 % 10 = 1
So 7776-66-1 is a valid CAS Registry Number.
